Cyanotype is a super simple way to create beautiful nature art. The easiest way to do it is by buying paper pre-treated in the cyanotype chemicals. Any of these are good options: https://www.amazon.com/cyanotype-paper/s?k=cyanotype+paper. You can also buy the chemicals and treat fabric yourself. Once you have your surface all set, you can pick botanicals to print with. Some of my favorites are ferns and tall wildflowers. Arrange your plants on your surface and place a piece of plexiglass over them to flatten the plants against the paper or fabric. Leave this in the sun for about 10 minutes. Remove the plexiglass and plants and run the paper or fabric through cold water mixed with lemon juice. Hang to dry. I've made countless pieces of artwork this way and also my favorite bandana. I'll look around for some pictures and post them below!
